Level Select - Up, Down, Down, Down, Down, Up, A + Start. The down-pointing spring has some weird behavior that appears to have been disabled starting with the September 14th build If Sonic hits such a spring and uses his death sprite for it, he will roll into a ball once he reaches the ground, and can shoot far from a quarter-pipe, stick to flat ground surfaces, and even clip below the floor into his death.ĭiscuss ideas and findings on the talk page. The screen doesn't scroll up or down when you look up or down for a certain period of time. If Sonic and Tails are both hit at the same time while carrying at least one ring, an overabundance of rings will pop out regardless of how many they actually possess.
The timer resets to 9:00 before hitting 9:59, allowing the player to test stages for extended periods. Locking on this prototype with Sonic & Knuckles will unlock the full Blue Sphere game. Spawned monitors can only be broken once per life/act. If Sonic has passed a signpost, entering and exiting debug will not allow the player to regain the ability to control him. Sonic retains his land speed if entering debug from water, and exiting to land. Entering and exiting debug while submerged will not reset Sonic's underwater timer. Sonic cannot enter debug when he is in his death animation. Sonic cannot enter debug while he is being knocked back. When Sonic is hit without rings, he'll only be knocked back The only way for him to lose a life is by drowning/falling into a bottomless pit. Sonic's speed and velocity don't reset when exiting debug.
Debug mode follows the logic of Sonic 1. The explosion sprites are as they are in Sonic 1. The ground speed cap from Sonic 1 is still present. The spike damage behavior works the same way as it does in Sonic 1. The spin dash is a work-in-progress, as Sonic and Tails can only charge it once further, the sound for when Sonic spins in Sonic 1 is heard as there is not yet a specific sound effect for the spin dash. The sprite of him getting up would later be polished and reused for when Sonic leaves his "lying on ground" idle animation. There is a mechanic where Sonic rebounds off walls if he runs into them at high speeds, using sprites that became unused by the Simon Wai prototype. The music and invulnerability last until the end of the Act. Invincibility doesn't show the star effect, though the music is still played. 2-Player mode is even less complete, due to all sorts of odd glitches and not being enabled for every Zone.
The AI is also much simpler: Tails copies Sonic's moves and makes no attempt to keep up with him. If Tails gets hurt, he can lose rings for Sonic. Further, Tails cannot complete a level on his own, since the game only loads the goal sign when Sonic approaches it.
At this point in development, Tails is quasi-independent: Player 2 is able to control Tails, except he will also follow Sonic.
